Mumford & Sons, deadmau5 and nonstop festival headliner Florence + The Machine tops the 2016 bill, as does Kings of Leon, who were supposed to perform at the fest in 2015 but saw their performance rained out. Also worth noting: Blink-182 is performing! Presumably, Matt Skiba will be filling in for the departed Tom DeLonge, but one can hold out hope for the Mark, Tom and Travis show, right?

Firefly returns to the Woodlands of Dover, Del. on June 16-19, 2016. Tickets go on sale this Friday morning (Nov. 20).
